ing to north.

11 a.m. Above clouds in Rhine Valley. No. 873
passed across and took up position ahead
and about a mile to port. Continued
to Schaffhausen, when suddenly lost
sight of 873. No. 875 about two miles
astern and about same height.

11.30 a.m. Arrived extreme end of lake and came
down to within 10 feet of water. Continued
at this height over lake, passing
Constance at a very low altitude, as
considered less likelihood of being seen.
Crossed lake and hugged north shore
until five miles from objective. Started
climb and reached 1,200 feet. Observed
twelve or fourteen shrapnels
bursting slightly north of Friedrichshafen.
Presumed these were directed
against No. 873.

11.55 a.m. When half a mile from sheds put machine
into dive, and came down to 700 feet.
Observed men lined up to right of shed,
number estimated 300-500. Dropped
one bomb in enclosure to put gunners
off aim, and, when in correct position,
two into works and shed. The fourth
bomb failed to release. During this
time very heavy fire, mitrailleuse and
rifle, was being kept up, and shells were
being very rapidly fired. Dived and
flew north until out of range of guns,
then turned back to waterside shed to
try and release fourth bomb. Bomb
would not release; was fired on by two
machine guns (probably mitrailleuse),
dived down to surface of lake and made
good my escape.

1.50 p.m. Arrived Belfort.'

The other account was given by a Swiss engineer who saw the raid from an
hotel near the Zeppelin sheds. He counted nine bombs which fell in an
area of 700 square yards round the works and sheds, and he said the
earth and debris were thrown up to a height of 25 feet. Each machine had
four twenty-pound bombs; one of Flight Lieutenant Sippe's bombs, as has
been seen, failed to release. That leaves two bombs of the twelve to be
accounted for; these fell on the sheds themselves, one greatly damaging
a Zeppelin, the other destroying the gas-works, wh
